Changes v1->v2: * Fallback to ISA default mcpu flag if custom one isn't supported by compiler. * Drop HSDK custom Kconfig options (choose between HSDK and HSDK-4xD) as we don't need it (at least for now). Instead we select ARC_LPB_DISABLE for both boards but it's totally OK as HSDK doesn't have LPB so disabling will be skipped by BCR check in runtime. * Add missing HSDK-4xD device tree bindings. Convert HSDK device tree bindings to json-schema.
